<div class="content">
Uses binary search to search for a value in an array.<br><br>
This method returns the array index of the value in the array, which must be sorted in ascending order.<br><br>
If the value is in between two elements of the array, this method returns a non-integer that interpolates the indexes of the two elements. For example, suppose the array consists of 3 elements [4, 6, 10]. If this method is used to search for the value 7, it will return 1.25.<br><br>
If the value is smaller or larger than all the elements in the array, this method returns the nearest index, which must be either 0 or the index of the last element of the array.
